摘要
The present invention relates to a method of propagating chicken infectious anemia virus (CIAV). This method involves providing a Marek's disease chicken cell line-CU147 culture and inoculating the culture with a chicken infectious anemia virus under conditions effective to propagate the virus in the culture. The present invention also relates to methods of isolating, identifying, and quantifying chicken infectious anemia virus in a sample which includes providing a biological sample, providing a Marek's disease chicken cell line-CU147 culture, incubating the culture with the biological sample under conditions effective to allow a chicken infectious anemia virus to infect the culture, and isolating, identifying, or quantifying the virus in the culture. The present invention also relates to a high titer vaccine formulation for chicken infectious anemia virus which includes an immunologically effective amount of chicken infectious anemia virus propagated in a Marek's disease chicken cell line-CU147 culture. Another aspect of the present invention is a method of immunizing poultry against chicken infectious anemia virus which includes administering a vaccine prepared from chicken infectious anemia virus propagated in a Marek's disease chicken cell line-CU147 culture in an amount effective to induce an immune response to the virus.
